Bruce Shapiro brought his Egg Bots. They draw pictures on eggs with felt tip markers. www.egg-bot.com/	They look like this.	And like this.	Bruce expaining how they work.
Some eggs that were created.	Close up of some eggs.	The egg plotters use controller boards that Brian Schmalz designed. Here are three different versions. www.schmalzhaus.com/	Close up of the boards.
The Egg Bot is driven from a laptop computer. I think the code is written in Liberty Basic.	Jeff Sampson's gyroscope test box. The Olimex board at the top just provides power and an RS232 convertor.	Close up of the box. The tall skinny metal can is a Panasonic gyroscope. The fat square metal can is a Gyration gyroscope. The board missing from the big DIP socket was a Melexis gyroscope.	Jeff Sampson's standardized processor board (on the left) and a custom 8 channel sonar board.
The standardized processor on a custom IMU board. The IMU has a Melexis Gyroscope, a Sparkfun 5 axis IMU board and a barometric pressure sensor module.	Here is a standardized processor board (which has my custom Robot Bus interface) connected to two other Robot Bus modules. The orange cable is a cross over which makes the module on the left the master.	Kai and Lewis Dickson's robot.	Jeff Sampson brought his motor controller project. It will eventually be a 3 or 4 channel motor controller that does PID control of each channel. It uses an Atmel XMega128A1 processor.
Close up of the prototype.	These two boards form the actual controller. I have a custom XMega prototyping board at the bottom. The top board has a small amount of logic and the motor and encoder connectors.	I also have the Olimex prototyping board that has two JRKerr PIC-ServoSC chips. I switch my motor back and forth from this controller to my controller to compare the performance. jrkerr.com/icproducts.html
